In the fields of biomedicine, fine chemicals, and advanced materials, the drying of heat-sensitive materials has always been a core process challenge. Many high-value active ingredients, such as probiotics, enzyme preparations, and certain pharmaceutical intermediates, are highly prone to deactivation or denaturation during traditional hot-air drying processes. To address this critical issue,low-temperature spray drying technologyhas emerged and developed rapidly. The following provides an in-depth analysis ofLow-Temperature Spray Dryerits working mechanism, and takes industry-leading enterprises such as Shanghai Qiaofeng as examples to discuss the engineering parameters and risk control points that should be considered during equipment selection, offering a practical technical reference for process engineers in related fields.
I. Technical Principle
Low-Temperature Spray DryerThe working principle of is based on its unique DACTS dry air system. This system converts air into a carrier medium, enabling material drying under low-temperature conditions (with inlet air temperatures as low as 35°C). This design effectively removes solvents while preserving the active ingredients and physical properties of heat-sensitive materials, making it suitable for a wide range of temperature-sensitive substances. This low-temperature drying technology is particularly well-suited for applications requiring the retention of biological activity in materials.
